Hereditary haemorrhagic telangiectasia.

Hereditary haemorrhagic telangiectasia (HHT) is a vascular dysplasia inherited as an autosomal dominant trait and caused by loss-of-function pathogenic variants in genes encoding proteins of the BMP signalling pathway. Up to 90% of disease-causal variants are observed in ENG and ACVRL1, with SMAD4 and GDF2 less frequently responsible for HHT. In adults, the most frequent HHT manifestations relate to iron deficiency and anaemia owing to recurrent epistaxis (nosebleeds) or bleeding from gastrointestinal telangiectases.

Effect of oral nintedanib vs placebo on epistaxis in hereditary hemorrhagic telangiectasia: the EPICURE multicenter randomized double-blind trial.

Epistaxis greatly affects patients with hereditary hemorrhagic telangiectasia (HHT). Although few systemic treatment exist, nintedanib, is a good candidate thanks to its anti-angiogenic activity. Our main objective was to evaluate the efficacy of oral nintedanib on epistaxis duration in HHT patients with moderate to severe epistaxis.

On-demand release of encapsulated ZnO nanoparticles and chemotherapeutics for drug delivery applications.

Nanomedicines offer high promise for the treatment of various diseases, and numerous novel approaches using nanomaterials have been developed over the years. In this report, we introduce a new strategy utilizing ZnO nanoparticles (nZnO) to trigger the rapid release of lipid-encapsulated therapeutics upon photo-irradiation with UV light (365 nm). studies demonstrate that encapsulation of nZnO effectively eliminates the cytotoxicity of nZnO, but this can be re-established upon release from the lipid coating.

Catch-Up Saccades in Vestibulo-Ocular Reflex Deficit: Contribution of Visual Information?

Objectives: Catch-up saccades help to compensate for loss of gaze stabilization during rapid head rotation in case of vestibular deficit. While overt saccades observed after head rotation are obviously visually guided, some of these catch-up saccades occur with shorter latency while the head is still moving, anticipating the needed final eye position. These covert saccades seem to be generated based on the integration of multisensory inputs.

Breast implant-associated anaplastic large cell lymphoma.

Breast implant-associated anaplastic large cell lymphoma is a subtype of non-Hodgkin's lymphoma that can occur around the surface of textured breast implants or in patients who have previously had textured breast implants. The condition should be suspected in cases of late-onset breast asymmetry and seroma formation around a breast implant. If the implant and surrounding connective tissue capsule is removed, the prognosis is usually very good.
